SPINDLE DEVICE.

Application filed July '7,

To all whom it may concern Be it known that I, WALTER L. Sirrri-r, a

citizen of the United States, residing at Gastonia, in the county ofGaston and State of North Carolina, have invented a new and usefulSpindle Device, of which the following is a specification.

This invention relates to a drive for spindles, one of the objects beingto provide a tension means whereby a band or belt utilized for driving aplurality of spindles can. be kept under proper tension. Here'tofore ithas been necessary to utilize an individual band for each spindle, andas these bands have become slack the yarn produced has been soft and thebobbins have not been sufficiently hard when wound. Bands heretoforeused hage also been objectionable because they are sometimes too tightand thus absorb power unnecessarily.

It is an object of the present invention to provide a drive which willoperate a plurality of spindles will maintain a uniform tension at alltimes, and affect a unir form twist of the yarn.

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the coinbination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a plan view showing in slightly exaggeratedform the drive mechanism combined with four spindles of the bobbinwinder.

Fig. 2 is an enlarged section on line 22, Fig. 1.

Fig. 8 is a section on line 33, Fig. 2.

Fig. 4. is a section on line 41- 1, Fig. 2.

Referring to the figures by characters of reference 1 designates thespindle bars of the machine between which is located the drive cylinder2. Spindles have been indicated at 3 each of them being provided with agrooved collar or sheave 4 as ordinarily. The device constituting thepresent invention is adapted to be combined with four of 1924.

the spindles, two upon each of the rails 1. This mechanism includes abracket 5, the upstanding portion of which is slotted. transversely asat 6 so as to receive an attaching bolt 7. By providing this slot thebracket can be adjusted laterally relative to the rail 1. Bolted orotherwise connecteii to the lower portion of the bracket is a hanger 8having superposed parallel depressions 9 in which are adapted to beseatedv parallel guide rods 10. These rods are clamped in thedepressions by means of a plate 11 and journaled on the hanger 8 is apulley 12. Slidably mounted on the upper rod are spaced sleeves 13formed on a carriage 14 and the lower portion of the carriage is forkedas at 15 so as to straddle and slidably engage the lower rod 10. Thecarriage is formed. vith a stud 16 to which is connected a chain orother flexible device 1.7 mounted on the pulley 12. This flexibleelement carries a weight 18 as shown.

The carriage is provided with a yoke 19 which extends over the hanger 8and also has one arm spaced from and lapping one side of the carriage asshown particularly in Fig. 1. This arm is formed in its inner side witha recess 20 having an overhanging lip 21 and another recess 22 is formedin one side of the carriage. In these recesses are seated bearing blocks23 preferably of hard wood in which are journaledthe ends of the shaft24 of a large pulley 25. It will be noted that when these blocks are intheir recesses one of them is overhung by one of the rods 10 so thatwhen the parts are properly assembled, it becomes impossible for theblocks to become dislodged.

An endless belt is extended around the pulley 25 and thence to thesheaves 3 on a pair of spindles on one of the rails 1, thence back tothe sheaves 4 on a pair of spindles on the other rail 1 and finallyaround the cylinder 2 and back to a pulley 25. Thus it will be apparentthat when the cylinder 2 rotates, motion will be transmitted therefromthrough the belt to the four sheaves engaged thereby so that fourspindles will be operated. The weight 18 pulls constantly on thecarriage 14 and, consequently, the pulley 25 will constantly pull on therod or belt engaged thereby so as to hold the belt under proper tensionand insure uniform winding of the bobbins. g

It will be understood of course that the hearing blocks can be removedreadily simply by lifting them out of the recesses in which they areseated and substituting others.

What is claimed is 1. A device of the class described including anattaching bracket mounted for lalei-a1 adjustment, a hanger connectedthereto, a clamping plate connected to the hanger, guide rods clamped atone end between the hanger and plate, a carriage mounted to slidebetween and along the guide rods, an arm at one side of and carried bythe carriage, there being recesses withinthe inner side of the arm andone side of the carriage, bearing blocks removably seated within therecesses, shaft journaled within the blocks, a belt engaging pulleyrotatable with the shaft and between the carriage and its arm, a pulleyupon the hanger, a weight, and a flexible connection between the weightand carriage, said connection being mounted on the pulley of the hangerfor holding the carriage normally drawn toward the hanger.

2. In a device of the class described a bracket for attachment to aspindle bar, a hanger depending from the bracket, a pulley thereon,parallel guide rods, means for clamping the rods at one end against thehanger, a carriage between and slidable along the rods, a weight, aflexible connection between the Weight and carriage and mounted on thepulley for holding the can riage normally drawn toward the hanger, anarm upon one side of the carriage, and a belt engaging pulley detachablyjournaled be tween the arms and the carriage.

In testimony that I claim the foregoing as my own, I have hereto altixedmy signature.

WALTER LEE SMITH.
